Valuing Medical Equipment

Establishing the Fair Market Value (FMV) of heavy medical equipment is a multi-layered process. Linear accelerators accrue many costs when adding up the various parts. To better understand how to form a proper valuation, keep reading to become familiar with commonly used appraisal terms.

Fair Market Value (FMV)
Also known as “retail” value, FMV is the price a buyer should anticipate paying to have the device relocated and installed at their location. Software relicensing, commissioning, and accessories required to operate the equipment are all extra fees.

Orderly Liquidation Value (OLV)
Sometimes referred to as “wholesale” value, OLV is the price a buyer can expect when selling an “as-is, where-is” product.

In Place Value (IPV)
Another name for IPV is “turn-key” or patient-ready value. It takes into account the values associated with the machine, including the cost of installation, commissioning, software licensing, regulation, accessories, and residual warranty coverage.

Some factors that impact the medical equipment’s valuation include:

  • Age
  • Configuration
  • Physical condition
  • Useful life left
  • Software version
  • Functionality
  • Removal path
  • Resale market demand
  • Wear and tear
  • Geography

Safely Using Linear Accelerators in Cancer Treatment

Linear accelerators are now widely used in treating a variety of cancers. A linear accelerator delivers directed X-rays or electrons to a tumor, destroying cancer cells while ensuring that surrounding tissue is protected. However, this type of radiation still poses risks, so how do manufacturers and operators ensure the safety of patients and operators?

All companies that manufacture linear accelerators have a strict quality control process. Systems are built to confirm that the machine will not deliver a higher dose than that prescribed by the radiation oncologist. Additionally, safety measures are designed into the linear accelerator that ensures it is impossible to turn the machine on without all the treatment conditions being met.

When a linear accelerator is installed, strict requirements must be met for the area it is situated in. For the operational staff’s safety, it is installed in a room lined with lead and concrete, and the controls for turning it on/off are situated outside of this room. Since the machine only emits radiation when turned on, this almost entirely eliminates the risk of accidental exposure.

At the start of each day and before any patient is treated, the radiation therapist makes sure that the linear accelerator is working correctly and performs checks for uniformity of the radiation intensity across the beam. In addition, a medical physicist conducts more detailed monthly and annual checks.

Another essential part of maintaining safety is keeping good records of patient exposure to the linear accelerator. All medical facilities using linear accelerators to treat cancer will ensure their staff are adequately trained and kept updated on the latest guidance on their use and safe limits for patient exposure.

Novel ‘Cure’ For Cancer Treatment

A new report published in Nature titled “Decade-long leukemia remissions with persistence of CD4+ CAR T cells” highlights a novel treatment called CAR T, which is being hailed as a “cure” for cancer by Dr. Carl June, the principal investigator for the trial at the University of Pennsylvania.

June said, “Now we can finally say the word ‘cure’ with CAR T cells.” In 2010, when the trial began, the idea for this sort of therapy “was way out there,” he added.

June and his colleagues reported that the CAR T therapy wiped out cancer in two out of the three initial early-trial patients, all of whom had chronic lymphocytic leukemia. Though the cancer disappeared, the CAR T cells stayed circulating through patients’ bloodstreams, almost guarding the body against future attacks.

In CAR T therapy, T cells (white blood cells that fight viruses) are removed from a patient’s blood and re-introduced after being genetically engineered to fight cancer. Patients’ T cells are taught to recognize and destroy B cells, a key player in cancer formation throughout the body. Without B cells – or cancer – patients require regularly-scheduled infusions of immunoglobulin infusions, which replenish antibodies.

Many people with blood cancer have benefitted from CAR T therapy, which has proved especially effective against acute leukemia. Roughly a third of patients who underwent the CAR T therapy have gone into remission, but many patients later relapse.

Dr. John F. DiPersio, chief of the division of oncology at Washington University in St. Louis, said, “The question is not only why some patients relapse or are resistant to therapy but why are some patients cured?”

He continued, “Oncologists don’t use words like ‘cure’ lightly or easily or, frankly, very often,” he said. “I guarantee that it’s not being used lightly. The patients we treated had far advanced disease,” he noted, adding, “the biggest disappointment is that it doesn’t work all the time.”

Beams Used in Radiation Therapy

The use of external beam radiation therapy is one of the most common forms of cancer treatments that a doctor or oncologist will recommend. This method involves radiotherapy equipment such as a linear accelerator that aims radiation from outside of a patient’s body and directly targets local areas of a cancer site. Various types of cancers can be treated with external beam radiation therapy, and depending on the unique characteristics of the tumor, a selection of systems and treatments will be formed for the best outcome. Not only are there different types of machines that can be used, but also the radiation beam used in external radiation therapy can come from three kinds of particles called photons, protons, and electrons.

Photons

The majority of radiation therapy machines use ionizing photon beams since they can reach tumors deep in the body. Photons are also used in x-rays, although they consume a much lower dose of the particle in comparison. The radiation that is delivered during photon treatment will damage the DNA of tumors and healthy cells alike. Radiation therapists aim to maximize the dose targeting the tumor while minimizing the radiation to nearby healthy tissues by creating different paths with multiple fields. To avoid overexposure to healthy cells, the treatment is generally given in stages over repeated scheduled sessions so that the healthy cells have time to repair.

Protons

Charged particle radiotherapy is an alternative method of radiotherapy that uses beams of protons or other positively charged particles such as helium, carbon, or other ions that are not photons. These types of beams can also reach tumors deep inside the body, but they perform differently than photons as they do not scatter radiation on their path and will stop once they reach the targeted tumor. Due to the physical characteristics of charged particles, it may be possible to cover the tumor area with only one radiation field, creating an advantage over the use of photons to spare more healthy tissues and cells. Clinical trials are continuing to compare the usage of these two energy types. There are cancer centers that are beginning to use proton beams in radiation therapy, but they have higher costs and require a larger space to fit the increased size of the equipment.

Electrons

Particles with a negative charge are electrons. Electron beam radiation therapy is designed to treat cancers like lymphoma and other tumors near the surface since these electrons do not go deep into the body. These therapy options can be done in two different ways:
  1. Spot treatment – This method is used for one or more cancerous spots on the body that needs treatment.
  2. Total Skin Electron Beam Therapy (TSEB) – This method is used when the entire surface of the skin needs to be treated. Other treatments called compensation treatments can be part of the treatment plan to guarantee that every area of the skin receives the proper dose required.

Solutions for Cooling Systems of a LINAC

LINACs are a type of particle accelerator that increases the kinetic energy of a particle that can be used in a variety of different areas such as scientific research or during radiation therapy to remove cancer cells of a patient. As with most medical and lab-related equipment, particle accelerators are negatively affected by thermal changes, especially with an increase of heat. It is of most importance to maintain temperature control of the equipment components to guarantee the integrity, performance, and reliability of the system. A solution that helps maintain temperature control is using a custom liquid cooling system. We will further discuss this option below so you can adequately care for your LINAC equipment.

How A LINAC Works

A medical linear accelerator (LINAC) produces and delivers a radiation beam using high energy x-rays or electrons to a targeted area to destroy cancer cells while carefully not damaging the surrounding normal and healthy tissues nearby. The medical equipment accelerates electrons in part of the accelerator called the waveguide and then allows the electrons to collide with a heavy metal target to create the high-energy x-rays. The radiation beams are shaped as they exit the machine to conform to the shape of the patient’s tumor. The patient lies on a movable treatment couch and the lasers are designed to be sure that the patient is in the correct position. The couch can move in a variety of directions along with the gantry – the part of the accelerator in which the radiation beam comes from.

Cooling System Needs

When using a LINAC during IMRT (intensity-modulated radiation therapy), the thermal consistency is necessary to maintain beam energy and stability. All the parts inside the equipment such as the tungsten target, waveguide, acceleration chamber, and the magnets need accurate thermal control to eliminate heat buildup and to allow the temperatures to remain the same for optimal usage for operation. Some of the parts within the machine, like the waveguide and filament material, require temperatures within .5 degrees Celsius. The solution to this is to install a liquid cooling system as the best option. In an IMRT system, the cooling path can be complicated. The water starts by cooling the charging drawer and oil pump. It then leads to the liquid cooling system that will decrease the temperature of the entire system, including the linear accelerator.

Types of Liquid Cooling

Liquid cooling systems are ideal for temperature control and stabilizing. They are designed to remove large amounts of heat that is generated in a densely packed electronic environment of a linear accelerator. It may cause concern that liquid coolant is so near all these electrical products but if the cooling system is designed and assembled correctly, there should be no issues. A few reasons these systems are more beneficial opposed to air-based heat exchangers is the ability to provide faster cooling, runs more quietly, and is more reliable with less downtime. Three options for cooling systems are:
  1. Liquid – Air Heat Transfer Configuration – a high-pressure pump that recirculates the liquid coolant and an air heat exchanger to remove heat in the liquid system
  2. Liquid – Liquid Configuration – the pump recirculates the coolant and the facility water is used for a liquid heat exchanger to remove heat from the higher temperature side
  3. Compressor – Based Chiller System – the pump recirculates coolant that is chilled to well below standard temperature

Should You Buy a Used Linac Over a New System?

Medical-grade Linear accelerators are investments, not an impulse buy. That being said, a linear accelerator is an essential tool in any oncologist office. Owners of a medical oncologist clinic have the option of purchasing a new linac system or invest in a used system, and there are advantages and disadvantages for both. You can essentially break the parameters into three (or more) situations:

Your Office Space

 

The space and size of your medical office or clinic is a good factor when deciding to go either used or new for a linac system. Smaller clinics will benefit from a used system, especially those with a small client-base that don’t move through more than a handful of patients a day. This also pertains to offices that are new and just getting started, or established offices that are small in space. Offices and clinics just starting up can go with a used system at first and upgrade to a brand-new system when the profits call for it.

Your Intentions

 

Not all offices and clinics revolve heavily around the use of a linac, but rather use it sparingly. This is a simple reason to go with a used system over a new one. Operating these systems can get expensive, and offices that heavily use a linac system with all the bells and whistles accompanying it have better use for a shiny new device. Conversely, those offices or clinics that only use it sparingly can go with a used model that is more stripped down to a model precisely tuned for their needs. You also may be a new office with the intention of having a higher-level model in the future, but current-day budgets don’t allow it, which calls for a more budget-friendly used system.

Your Experience

 

Is your office or clinic moving? Do you have any intention of moving in the next year or so? Are you generally a busier clinic with many patients? New linac systems are great for busier and more modern clinics but for those with the need for backup units a used system is better to keep on hand for when a new system breaks down, especially with all the parts that go into such a device. Similarly, if you’re a clinic that has plans to move everything it may be easier for the future if you go with a used system that will be installed only to be uninstalled for a big move. Even higher-tiered clinics can find themselves moving, so this is something to keep in mind when setting up a clinic initially when starting up.

Medical grade linear accelerators are a product in which all oncologist clinics should be investing. That being said, making a purchase can be smarter when going with a used system rather than new; it just depends on your office space, intentions with the system, and overall experience of running your clinic.
